magnetite separation cost for phosphate
AMIT 145: Lesson 3 Dense Medium Separation – Mining Mill ...
Considering the above results, a cost-effective protocol for P removal and recovery from SE was established by the repetitive utilization of Mag-MM and regeneration solution, magnetic separation of P-loaded or regenerated Mag-MM, and the recovery of P as calcium phosphate from exhausted regeneration solution.

Phosphate modified magnetite@ferrihydrite as an magnetic ...
Selection of natural magnetite as iron source for ferrihydrite synthesis and as magnetic core is believed to save the cost of adsorbent. Then, phosphate was loaded on Mag@Fh by impregnation-heating treatment to produce Mag@Fh-P. Batch adsorption experiments revealed that the Cd(II) adsorption on Mag@Fh-P could reach equilibrium within 60 min ...

Magnetite seeded precipitation of phosphate - ScienceDirect
The possibility of phosphate removal from wastewater by magnetic separation was first described by De Latour et al. They investigated the magnetic elimination of phosphate by precipitation in a system including the using of aluminum sulfate and montmorillonite, and of Fe in the form of FeCl 3 in addition to magnetite powder, .

sized and explored for its phosphate removal properties. The synthesis method was simple and scalable, and the prepared material had a high value of saturation magnetization, indi-cating the easiness of magnetic separation of the nanoparti-cles from the liquid phase. The Al-MNP also showed high adsorption capacity toward phosphate removal. 2.

As shown in Figure 10, the phosphate and starch in the wastewater can be adsorbed on magnetic seeds surface, and then separated from the wastewater by magnetic separation. The phosphorus and starch content in the wastewater are reduced to 1.51 and 9.51 mg/L, respectively, and the removal rate reaches more than 75% [ 102 ].

Pilot plant tests at various sewage works showed that magnetic separation reduces the total-phosphate concentration to values as low as 0.1-0.5 mg/l. The system will be demonstrated in two full-scale plants with a capacity of 300 m 3 /h and 600 m 3 /h, respectively. The costs of magnetic phosphate removal (Dfl. 12,- to 18,-) are competitive ...

The capital cost, which is also high, would be reduced if roasted ore were processed in an existing magnetic separation plant. However, processing of reduction-roasted ore in a conventional taconite plant would require some modifications, because artificial magnetite has a higher remanence and coercivity than natural magnetite.
